Drop AMD module support

CommonJS Modules are now the only supported format. Any loader that can
load CommonJS Modules should be able to load rest.js. curl.js users can
use the cjsm11 loader.

Bundlers like Browserify and WebPack can also be used to consume rest.js

 - MAJOR: Drop hard when.js dependency in favor of ES6 Promise API. See https://github.com/cujojs/when/blob/master/docs/es6-promise-shim.md to use when.js as an ES6 Promise polyfill.
+- MAJOR: AMD modules are no longer supported. curl.js users can use the cjsm11 loader, see https://github.com/cujojs/curl#api-at-a-glance
 - Moved path token param replacement from the clients into the `rest/interceptor/params` interceptor, which is also deprecated. The behavior will no longer be applied automatically in the client. Using the `rest/interceptor/template` interceptor is far more powerful and preferred.
 - Fixed an issue preventing uri template exploded values from expanding correctly.
 - Update tested environments:
